Prerequisite: Warlock, Dark pact By becoming a demonbinder, you sacrifice your immortal soul for the instant power granted by the abyss. You draw demonic agencies inside yourself, triggering vile transformation that bestows not only a sampling of a fiend's power, but also leaves a resemblance to that fiend. Constant exposure to these creatures leaves a stain on your soul so foul that no act of restitution will ever cleanse it.
